359703 A sky laboratory of mass \({3 \times 10^{3} {~kg}}\) has to be lifted from one circular orbit of radius \({2 R}\) into another circular orbit of radius \({3 R}\). Calculate the minimum energy (in \({\times 10^{10} {~J}}\) ) required if the radius of earth is \({R=6.4 \times 10^{6} {~m}}\) and \({g=10 {~m} {~s}^{-2}}\).
